Sample assessment
The feed was barium titanate powder. No starting size distribution, crystalline phase specification or application acceptance test was supplied.
Analyst consideration: For barium titanate, the distribution tail is a useful assessment alongside the median because the recorded objective concerns fine powder. Tooling contamination and preservation of any intended ceramic properties require separate checks.
Recorded objective
Meet a recorded 0.8 µm fineness requirement; the target statistic was not specified.
Equipment and selection
The machine entry is XQM. TENCAN Vertical square planetary ball mill is associated at the recorded series level. No exact housing variant is inferred from jar capacity or an abbreviated machine label.
Test setup
| Jar entry | Zirconia 250 |
|---|---|
| Media entry | Zirconia 250 |
| Media-charge notation | 3-220/8-60 |
| Sample-load entry | 50 (unit not stated) |
| Controller speed setting | 550 |
| Cycle notation | 5/1 |
Unlabelled jar, media and load numbers remain source notation, not assigned units. Controller settings are not certified rpm. The cycle notation has no independently stated timing unit or reversing definition.
Recorded procedure and results
The source lists a zirconia jar and zirconia balls. Water, 70 g, was added and milling continued for two hours. The procedure records D50 = 0.5 and D90 = 0.7, with no explicit unit repeated beside these two values. The result column is marked accepted against the 0.8 µm target.
Interpretation
The pair of distribution readings is retained exactly, with its unit limitation. Even if their units are confirmed as micrometres, D90 would describe the distribution rather than establish an all-particle 0.8 µm ceiling.
Practical precautions
Confirm analytical units and the target statistic before a repeat. Record sample dispersion and check recovered powder characteristics independently of the particle-size acceptance.
TENCAN alternatives to evaluate
TENCAN Laboratory Full-Directional Planetary Ball Mill. For barium titanate, an full-directional wet comparison can retain the 70 g water addition and two-hour distribution check. Confirm the D50/D90 units before comparing the platforms. QXQM changes suspension redistribution through assembly tumbling. That gives a concrete comparison of media–slurry contact at the same sampling point, rather than implying that the alternative inherently yields a lower D90. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM source entry; only recorded tested series/configurations are related. No jar-volume inference.
